Photoshop: Remove Zero Pixel Boundary Between Layer Selections

If I select a subject using no feather (or 0.2 pixels), create a new layer with it (cntl J), then select the new layer together with the old one, and then deselect the new one, I obtain marching ants for the subject on the orginal layer. If I then delete within the selected area, I get one layer with just the background, and a second layer with just the subject. If I then make both these layers visible, but no others, I see a zero pixel outline between the two (even with no feathering, as I said). I want to get rid of this, as it's causing problems when I want to blur only the background, as it gives messy edges. How do I achieve this?

Are you viewing the image at 100%, or zoomed out (subsampled view, where such an outline is unavoidable)?

Also, you should avoid reusing masks like that -- don't cut and delete, because that makes it much more likely to have artifacts along the edge. Just cut or copy.

And remember that you can invert masks in the Mask panel.
